HOLDING FIXTURE FOR CYLINDER HEADS Filed March 17, 1960 Thomas JWaggoner 1 N VEN TOR.

BY @mwifim United States, Patent o 3,048,387 HOLDING FIXTURE FORCYLINDER HEADS Thomas J. Waggoner, 124 W. Bell St., Pharr, Tex. FiledMar. 17, 1960, Ser. No. 15,702 2 Claims. (Cl. 269-51) This inventionrelates to improvements in holding fixtures for cylinder heads ofinternal combustion engines.

The primary object of the invention is to provide a fixture forattachment to a bench, table, or the like, to hold a cylinder head inelevated, suspended position and which is universally adjustable toadjust a cylinder head thereon into substantially any desired angularposition to facilitate grinding of valves in their seats, or repair workon the cylinder head.

Another object is to provide a fixture for the above purposes which iseasy to adjust, safe to use, simplein construction and inexpensive tomanufacture and service.

These together with other objects and advantages which will becomesubsequently apparent residein the details of construction and operationas more fully hereinafter described and claimed, reference being had tothe accompanying drawings forming a part hereof, wherein like numeralsrefer to like parts throughout, and in which:

FIGURE 1 is a fragmentary perspective view of the holding fixtureattached to a bench;

FIGURE 2 is an enlarged view in horizontal section taken on the line 22of FIGURE 1; and

FIGURE 3 is a fragmentary view in horizontal section taken on the line3-3 of FIG. 2.

Referring to the drawing by numerals, the holding fixture of thisinvention, and which is designated generally by the numeral 1,comprises, in its preferred embodiment, an attaching plate or base 3,preferably rectangular, with a central post rising therefrom andpreferably formed integrally therewith, said post being substantiallycylindrical and of a material diameter. The plate 3 is adapted to bebolted, as at 7, flatly on a bench 9 preferably adjacent one edge of thebench. I

An elongated bar 11, or like member, with a longitudinal central slot 13therein is provided for supporting a. workpiece in the form of acylinder head 15 which may be secured to the front side of said bar bybolts 17 passing through said slot 13 and whereby the cylinder head 15may be secured to the front side of the bar 11 in longitudinallyextending position for adjustment longitudinally along said bar 11.

Means is provided for connecting the bar 11 to the post in spacedrelation thereto comprising a reversible slide rod 19, or similarmember, longitudinally and rotatably adjustably extending transverselythrough the bore 20 in post 5 and retained in adjusted position by a topset bolt 21 in the post 5, and a joint 23 connecting the bar 11 to saidrod 19.

The joint 23 comprises a segmental plate 25 on the outer end of the rod19 coplanar therewith and provided with circumferentially spaced,transverse bolt holes 27 therein, a bifurcated rear arm 29 extendinglaterally from the center and rear side of the bar 11 coplanar therewithand straddling the segmental plate 25, a pivot bolt 31 connecting thearm 29 to the segmental plate 25 for swinging thereof and of the bar 11on the segmental plate 25 about an axis transverse to the rod 19 intodifferent angular positions, and a bolt 33 extending through said arm 29and through a selected bolt hole 27 for securing the arm '29 in adjustedposition on said plate 25.

As will be seen, the rod 19 provides for horizontal adjustment of thebar 11 and a cylinder head 15 on said bar, and for rotation thereofabout a horizontal axis, whereas, the joint 29 provides for swingingadjustment of the bar 11 and head 15 so that the head 15 may be soadjusted for variably positioning the same as occasion "ice may require.Also, when the plate 3 is positioned adjacent the front edge 35 of thebench 9, the bar 11 is positioned forwardly of the bench 9 to suspend acylinder head 15 clear of the bench so that it can be freely adjustedwithout interference with the bench.

An important advantage of the invention, beside providing for holding acylinder head in substantially any desired position is that the fixturemay be readily taken apart by removing the bolts 31, 33 to disassemblethe joint 23, and removing the rod 19 from the post 5 by loosening thebolt 21. Then the parts may be assembled in a compact bundle forcarrying or storage in a small space.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the-art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

1. A cylinder head holder comprising a horizontal 7 base, means forsecuring said base on a support, an essentially solid cylindrical postof a material diameter fixed on said base and having a bore extendingdiametrically through its upper portion, a cylindrical, horizontal rodreversibly mounted for rotary and sliding adjustment in the bore, a setbolt threadedly mounted in the upper end portion of the post andengageable with the rod for securing same in adjusted position, a bar,means for mounting said bar for swinging adjustment on the rod, andmeans for mounting aworkpiece on said bar, the second-named meansincluding a segmental plate integral with one end of the rod, said platehaving an inner opening therein and further having circumferentiallyspaced marginal openings therein, a bifurcated arm on anintermediateportion of the bar straddling the plate and having an opening thereinaligned with the inner opening, a bolt in the aligned openings pivotallyconnecting the arm to the plate, said arm further having an openingtherein selectively registrable with the marginal openings, and a boltin the registering openings securing the arm in adjusted position.

2.
